To all whnnt it nut 1 concern:

Be it known that we, MAURIcE GEORGE PLANE, residing at Gordon Villa, Barrington Road, and WILLIAM IIENRY PLANE, residing at Arrol Villa, Military Road, Colchestcr, county of Essex, England, subjects of the King of Great Britain and Ireland, have invented certain new and useful Improvements in and Relating to Positive-Feed Mechanical Lubricators, of which the following is a specification.

This invention relates to th-atclass of oilfeed apparatus in which the oil is fed positively by a pu mp to the parts of the machine or engine w ich are to be lubricated, said apparatus consisting of a number of elements capable of inde horizontally on t e radii of a circle, the elements being so arranged as to'produce an ap paratus by which each one of a large number of bearings or cylinders may be sup lied with the kind of oil suitable to it, whic shall occupy a minimum amount of space, which shall ave a minimum number of working parts, and which shall be capable of being coupled up to the engine by a belt or some other suita le means, so as to be automatic in action, and so that the supply of oil shall vary, if required, directly as the speed of the moving parts.

The apparatus is single-acting and consists of a series of cylinders located horizontally on the radii of a circle and mounted in a casing, so that their open ends converge toward a common center. In these cylinders plungers are fitted which are driven by an eccentric fixed on a vertical shaft mounted in bearings in the casing and revolving at the common center above referred to. Each of the cylinders forms a pump, which may be supplied with oil from a source under independent control and which may supply an independent bearing or hearings or the interior of a cylinder.

The invention consists, further, in combining with this arrangement of pumps an oilcontaining vessel carried on the casing over the pumps in any suitable manner, said contain ng vessel being, if necessary, divided internally by radial partitions into as many compartments as there are kinds of oil to be supplied, the compartments communicating endent control arranged- 'dened metal, arranged to They with their respective pumpsat their lower ends by means of control'valves and sightfeeds.

shown in Figs. 1 and 3. Fig. 5 is a plan view,

partly in horizontalsection, of another form of construction which we adopt of driving the pumps from the eccentric. Fig. 6 is a In the accompanying d rawin gs, which illus- W'ILLI A M HENRY PLANE, OF COLCH ESTER,

View, partly in section and partly in eleva- I tion, of Fig. 5. v

Referring to Figs. l to 6, A is a casing in which is mounted a vertical spindle B, which is driven through bevel-pinions by the wheel C, which maybe connected by a belt or otherwise to the engine. On the spindle is mounted an eccentric D. A number of cylinders E E are arranged horizontally round the casing A, being screwed in or otherwise suitably fastened. In these cylinders are arranged plungers F, with heads F, preferably of harbear against and be driven by the eccentric D. The plungers are held extended from the cylinders and pressed against the eccentric by means of springs G.

In Figs. 5 and 6, which illustrate an alternativemethod of driving the plun ers, the springs are dispensed with, and the heads F of the plunger are adaptedto engage with a groove D in the upper surface 0 the eccentric D. It is obvious that other means may be employed-to connect the plunger-heads. may, for instance, be attached to a strap surrounding the eccentric.

The oil is admitted to each cylinder by an aperture H, leading from the sight-feed K and control-valve L. The plunger itself acts as a valve to the aperture H.

A cylindrical hollow valve M (illustrated on an enlarged scale in Fig. 4) serves to close the exit N, which communicates With the delivery-pipes. On the return stroke of the pump the valve M is forced forward to follow the plungers partly by the sprin 0 behind each valve M is forced forwar vacuum created by the plunger. The forward movement is limited by a stop P, screwed into the cylinders and engaging with a slot Q, cut in the side of the valves. When Valve M reaches its foremost position, the plunger leaves the valve and travels on to the end of its stroke, whereby it uncovers the inlet-ports H, and the oil is drawn in partly by the vacuum created by the plunger and partly by gravity. On the delivery-stroke of the pump the plunger closes the inlet-ports H and compresses the oil in the cylinders between the valve M and plunger F until the pressure is such that it overcomes the resistance of the spring O,v whereby the valve'M is forced back and uncovers the exit-ports, through which the oil is discharged and forced to any part of the machinery.

The control-valves L are fastened in the drum B. This drum is screwed to the top of the casing A, said drum being, if necessary,

- divided internally into a number of compartments by radial partitions S. In the instance shown there are a four compartments, each supplying two pumps. The drum is closed by a cover T l It must be understood that the drum may be so divided that each compartment supplies a single .pump.

- Mechanical lubricators constructed on these lines are positive, effective, and economical, lubrication only taking place when the spindle B is operated, the oil being fed Whatwe claim as'new, and desire to secure by Letters Patent of the United States, is

1. In a mechanical lubricator, a supporting-casing, a plurality of radial cylinders fit: ted to and project' from the casing on the exterior thereof, e a ji of said cylinders having an oil-inlet and an oil-outlet, a normally closed cut-ofli' for the outlet of each cylinder, a plunger working in each cylinder and arranged to operate as a cut-off for the inlet -a spring-projected plunger Working in each cyhnder against said spring-pressed cut-off, the inner ends of the plungers being ex osed inside of the casing, and a drivi housed inside of said casing and inc uding a cam member engaging the exposedinner ends of all of said pl ers.

In testimony w ereof we'have aflixed our signatures in presence of two witnesses.
